网络定义错误：bond0：接口“eno2”未定义

当我尝试应用 netplan 时出现此错误。eno2 存在，但 netplan 说它未定义。

    renderer: networkd

            bond0:
                    interfaces: [eno1, eno2]
                    addresses: [192.168.0.104/24]
                    gateway4: 192.168.0.1
                    parameters:
                            mode: 802.3ad
                    nameservers:
                            addresses: [192.168.0.2]
                    dhcp4: false
                    optional: true

尽管该设备存在于内核级别，但您必须在 netplan yaml 中提供配置，以定义它供 netplan 使用。否则 netplan 将不会假定此名称的内核设备是您想要的。

network:
  version: 2
  renderer: networkd
  ethernets:
    eno1: {}
    eno2: {}
  bonds:
        bond0:
                interfaces: [eno1, eno2]
                addresses: [192.168.0.104/24]
                gateway4: 192.168.0.1
                parameters:
                        mode: 802.3ad
                nameservers:
                        addresses: [192.168.0.2]
                dhcp4: false
                optional: true
